The place is super close to BTS (main train line in Bangkok), that's what you want. You pay a bit less because it's not in the center, yet you get everywhere easily without traffic jams. Location is the prime plus of this place.
Also, it is quiet to sleep well at night, looks exactly like in the pictures and has the needed equipment. The equipment worked without any problems. Wi-Fi was super fast.
Bird answered always quickly to all inquiries and sent detailed instructions for everything you would need.
Note, though, that you pay extra for electricity when choosing this place, for us it was around 17€ for 28 days (we haven't used it much, though). But that was communicated in advance and seems to be commonplace in Bangkok when you book an Airbnb.
